In drinking water, ppm ≈ mg/L, ppb ≈ µg/L and ppt ≈ ng/L. Calculated hardness in grains per US gallon (gpg) = mg/L as CaCO₃ ÷ 17.118, rounded to one decimal. ND means below the reporting limit, not zero.

MCL is an enforceable contaminant limit; MRDL is a disinfectant limit. A secondary guideline concerns aesthetics. TTHM/HAA5 compliance uses locational running annual averages; read the utility’s notices as well as individual results.

PFAS results are compound-specific. Source monitoring, entry-point samples and tap tests are different. A detected result does not identify every PFAS compound or establish the level at your home. Read the original report for context and current utility notices. EPA PFAS benchmarks and implementation ↗

More about your local water

What this means for your home

Anderson relies on groundwater associated with local creek and river aquifers. That source description does not establish results for a separate Madison County utility or private well.

A home hardness test is needed because the report does not publish a numeric hardness reading. Lead and copper concerns need tap-specific information as well as a clarified utility table.

Filter vs. softener: what each doesPlan installation with your plumber

A useful local question

Why are Anderson’s lead and copper results flagged?

The report’s printed percentiles, ranges and counts over the action level do not agree. We show the reported percentiles in the full table with a clarification note rather than treating the entries as a dependable description of every tap.

Sources and methodology

We keep each utility’s results separate, show the reported sample year, and distinguish averages, maxima and tap-sampling percentiles. Hardness classifications use USGS ranges. Missing data stays unknown.
